IMPROVEMENT IN s'rALK AND KrNnLINe-woon corren.

The Schedule referred to in these Letters Pal-.eht and making peut of the samel To all whom lit may concern.-

Be it known that I, GEORGE B. HAMLIN, of Wilvlirnautic, of the county of Windham, in the State of Connecticut, have invented certainnew and useful Improvements in Machines for Cutting Corn-stalks, Kindling- Wooth'tc,and I'do hereby declare that they following is a full and exact description thereof, reference being had to the accompanying drawing making palt of this application. v

My invention relates t6' a new machine for cutting up .corn-stalks, brush,or kindling-wood, &c.

" y Previous to my invention numerous machines have to this end my jnvention consists inthe employment,

in connection with a suitable table for the 'support of the material, of one or more cutting-edges or knives, so arranged in a rotary holder as to effect a draw-cut' on the material, as will be presently more fully eX- plained.

` To enable those skilled to make and use my invention, I will proceed to more fullyexplain the construction and operation of a machine embodying it.

. In the accompanying drawing- Figure 1 is a side view.

Figure 2, a top view and Figure 3, a vertical section, at :t x, fig. 2, of a machine made according to my invention.

In the several gures the same part is designated by the same letter of reference.

A is the main frame of the machine, in which is folmed a suitable table, B, and in which are mounted the working parts of the machine.

C and D are respectively the main and auxiliary driving-wheels, which are mounted ox'l suitable shafts, ef, to either of which the motive power is applied.

Between the wheels C D is locateda friction-wheel, G, which is driven by both C and D, and is fast on the shaft h, as clearly shown. v

The wheels C D are handed together by a belt, I,

and the shaft of one of them, and also shaft h, mounted in movable boxesg'j and k, so that the`- wheels D and G canmove slightly toward and from wheel C,'and toward and from each other, to neutralize any irregularities, and keep always in perfect gear.

`The system of driving-wheels shown and alluded to need not be more minutely describedv here, as it' iorms the subject of another application by me, where it will be found `fully explained.

in, which are securely fastened thereon, and in the peripheries of which is seeureda knife-blade or cutter', 0. This blade, as will be seen, is .so shaped and arranged as to run diagonally to a plane passing through the axis of the disks m, and so `that it will A'pass by the stationary edge p with a shearing mot-ion, (see figs. 2 and 3.) Y

Themetallic edge or stationary critter p is arranged the rotary knife o to work against. It will vbe seen that the top surface of the tableB, on which the material is placed, is in a' plane, or at a level, f'ar below that in which the axis of the shafthis located, so that any point in the cutting-,edge of knife o moves in an are Athat bisects the plane of the table at a very acute angle, instead o f near-ly a right angle, asin other cutting-machines.

the stationary shearing-edge p, far below the plane in which the axis of shaft h is placed, and the diagonal arrangement of the blade o, any-material, stalks, sticks, Sec., placed on the table B, and fed to the cutashion of the cut produced in cutting with a drawing-knife by thehand.

stood to be as follows :d

Motive power being applied to the main shaft e, the wheels C D cause the wheel G and its shaft lato be rapidly rotated, and the disks or heads m m, with their cutter-blade o, are moved in the direction indicated by the arrow, Iig. 3. The stalks, or other materials to be cnt, are placed on the table B, and fed in the direction indicated by the arrows, tig. 2, toward the cutting mechanism, where they are cut off,- and the cut stock discharged downward and outward from the table.

AlthoughI have' shown only one knife o, and have found it sufficient, in amachine driven by myiln- -proved gearing system, more knives may, of course, be Y used, if deemed expedient, for some kinds of work.

The details of construction will depend upon the size of the machine, the velocity-at which the cutting mechanism is designed to rum-and the character of the work-to be done, and may be varied according to the judgment of the engineer or mechanic.

The peculiar driving mechanism shown I have found admirably adapted to this kind of machine, but my invention may be embodied in a machine having any other driving mechanism, the gist of my invention resting in the idea of the vdrawing and shearing cut, produced by havingthe table, on which the stock to be cut rests, arranged below the level of the shaft of the cutter-heads, and the knife arranged diagonally on the heads m, or obliquely to the plane of the table.

On the shaft h are two heads or circular disks, m

as seen, on the edge of table B, and' merelyserves for By this arrangement lof the table or support and` ters, will be cut off with a long drawing ont, afterthc The general operation of the machine will be underr- Having fnlly explained the nature of my invention, B, the whole constructed and arranged to operate as so that one skilled can make and 'use a machine emand for the purposes set forth. hodying it, In testimony whereof I have hereunto set my hand That I claim as new, and desire to secure by Letand afxed my seal this 17 th' day of June, 1870. ters Patent, is- In combination with the friction driving-wheels G Witnesses: GEORGE B. HAMLIN. and D, and shaft 71, the inclined rotary cutter-blade S. N. BELL, or blades o, stationary cutting-edge p, and feed-table H. E. BURNHAM.
